My inveniion relates to apparatus for eleriri"" heating W11 n cenidcrwith cylinders as n strep n riiesnrnc.

By touching aportion of the heaied circle on the cylinder with a cold iron, the baitis readily cracked off.

Afterthe bait has been detached from the cylinder the wire nnhoolicd, and thecurrent switched .off, the attendant swings ihe section 9 oi Lhe arm 8out away from the cylinder so that the rear face of the holder Willclear the cylinder, nnd pushes the trolley along the track until itreaches the proper place to crack (iii a section of the cylinder, saidplace being indicated by the dotted line 28 on Fig. 1. The cylinder iscracked off at the line 28 in the same manner that the halt was crackedoff.
